Incamake ya alumina yakozwe
Alumina yakozwe, izwi kandi nka bauxite yakozwe, yitwa activated alumina mu Cyongereza. Alumina ikoreshwa mu byuma bitunganya ubusanzwe yitwa "activated alumina". Ni ikintu gikomeye gifite imyenge myinshi, gitatanye cyane gifite ubuso bunini. Ubuso bwacyo bufite imyenge mito bufite imiterere ikenewe mu gukaraba, nko gukora neza kw'amazi, gukora neza k'ubushyuhe, nibindi, bityo ikoreshwa cyane nk'imashini itunganya ubushyuhe n'imashini itwara imiti.
Alumina ifite umuvuduko wa alumina uhinduka uruziga, ifata amavuta yo mu bwoko bwa spherical activated pressure ni utuntu tw’umweru dufite imyenge. Alumina ifite ingano imwe y’uduce, ubuso bworoshye, ifite imbaraga nyinshi mu byuma, ifite hygroscopicity ikomeye, ntibyimba cyangwa ngo ivunike nyuma yo kwinjiza amazi, kandi igumaho idahinduka. Ntigira uburozi, ntihumura, kandi ntishobora gushonga mu mazi na ethanol.
Alumina
Ntishobora gushonga mu mazi kandi ishobora gushonga buhoro buhoro muri aside sulfure. Ishobora gukoreshwa mu gutunganya aluminiyumu y'icyuma kandi ni ibikoresho fatizo byo gukora ibicanwa, porcelain, ibikoresho birwanya ubushyuhe n'amabuye y'agaciro y'ubukorano.
Alumina ikoreshwa nk'inyunganiramirire, ikora katalyst n'itwara katalyst yitwa "activated alumina". Ifite imiterere yo kuba imyenge, gukwirakwira cyane n'ubuso bunini bwihariye. Ikoreshwa cyane mu gutunganya amazi, peteroli, imiti myiza, ibinyabuzima n'imiti.
Ibiranga alumina
1. Ubuso bunini bwihariye: alumina ikora ifite ubuso bwihariye. Mu kugenzura neza sisitemu yo gutwika alumina, alumina ikora ifite ubuso bwihariye bungana na 360m2 / G irashobora gutegurwa. Alumina ikora yateguwe hakoreshejwe hydroxide ya aluminiyumu ya colloidal yakuweho na NaAlO2 nk'ibikoresho fatizo ifite ingano nto cyane y'umuyoboro n'ubuso bwihariye bungana na 600m2 / g.
2. Imiterere y'ingano y'imyenge ishobora guhindurwa: Muri rusange, ibicuruzwa bifite imyenge iringaniye bishobora gutegurwa hakoreshejwe hydroxide ya aluminiyumu yonyine. Ibicuruzwa bito bishobora gutegurwa hakoreshejwe aluminiyumu ikora hakoreshejwe kole ya aluminiyumu, nibindi, mu gihe aluminiyumu nini ishobora gutegurwa hakoreshejwe ibintu bimwe na bimwe by’umwimerere, nka ethylene glycol na fibre, nyuma yo gushya.
3. Ubuso bufite aside kandi bufite ubushyuhe buhamye.
Imikorere ya alumina ikora
Alumina yakozwe iri mu cyiciro cya alumina y'ibinyabutabire, ikoreshwa cyane cyane nk'iyungurura amazi, isukura amazi, iyungurura amazi n'iyungurura amazi. Alumina yakozwe ifite ubushobozi bwo gukurura amazi mu buryo bwihariye muri gaze, umwuka w'amazi n'ibindi bintu bivamo amazi. Iyo amazi yuzuye, ishobora gushyuha kuri dogere 175-315. D egree. Gukurura no kongera gukora bishobora gukorwa inshuro nyinshi.
Uretse gukoreshwa nk'umuti wo koza amavuta, ishobora kandi kwinjiza umwuka w'amavuta uva muri ogisijeni yanduye, hidrojeni, dioxyde de carbone, gaze karemano, n'ibindi. Ishobora kandi gukoreshwa nk'umuti wo koza amavuta n'umuti wo koza amavuta ndetse no nk'inkunga mu gusesengura chromatographic.
Ishobora gukoreshwa nk'ikintu gikuraho fluorine mu mazi menshi yo kunywa afite fluorine (ifite ubushobozi bwinshi bwo gukuramo fluorine), ikintu gikuraho fluorine mu guterura alkane mu gukora alkylbenzene, ikintu gikuraho aside no kongera kuvugurura amavuta ya transformer, ikintu gikuraho gazi mu nganda zikora ogisijeni, inganda z'imyenda n'iz'ikoranabuhanga, ikintu gikuraho umuyaga mu bikoresho byikora, n'ikintu gikuraho fluorine n'ikintu gisukura mu ifumbire mvaruganda, kumisha peteroli n'izindi nganda.
